JFP, just got the cayman back after complete engine overhaul. The cracked cylinder was resleeved and I was told all main components were replaced . Just after two days of getting the car back and 250miles the car suddenly started losing power on the highway and a flashing check engine light came on. Had the car towed back to independent service where it’s stil there. I’m told it’s misfire on cylinder 5. Cylinder 6 was re sleeved during the overhaul . After reading some posts could a crankshaft position sensor cause a misfire along with flashing cel ?
Hi JFP, so a simple O ring on oil cooler can drain all coolant into oil tank? So my situation is this: AOS full of oil and that was replaced codes gone. started car was fine after about 3 miles white smoke from exhaust engine losing a bit of power drove it straight home which I was only driving in neighborhood. intermix coming out of exhaust in large amounts. pure coolant leaking from O2 sensors and cats and sport exhaust baffle all on driver side. only cel code is for misfire on cylinder 6. took out all spark plugs and they all look good except a small micro pin drop of coolant on spark plug cylinder 6. No signs of leaks anywhere else except intermix from oil tank , coolant from driver side areas mention above. Coolant tank has no oil in it would that be somewhat of a good sign? I can take out oil cooler if you think that will help?
Hi Silver tt, I’m no engine expert but if my coolant drains straight to the oil tank what does that seem most likely it could be? Do you think the motor can still be rebuilt ? The person i was referred to said it could most likely be rebuilt but then after reading what you had to say with cylinder 6 same with my case having misfire I️ want to make sure if all possible before paying all the labor to dismantle to find out motor is not able to be rebuilt . ThAnks !!
Hi Wizard! Thanks for the reply. Just got it open to use small vice grip and pull super super hard and it pop right open. I mean with all my force. So for anyone trying this for me it took two hands and vice grips. Didn’t have to take front shell off either . Was able to remove palstic liner by jacking the car up and removing a total of 7 torx screws.
Got a dead disconnected battery and dead motor. Found front driver release cable but pulling on it pretty hard and it’s not releasing the front hood. How much pressure to you have to pull?? I’m pulling pretty hard with pliers and no success.
Hi Loren yes , they said there’s none in US or Germany. I would have to either do a full rebuild buying individual parts or just find a decent motor to drop one in from a salvage yard or eBay . Thanks and i will not use LA dis.
Hi guys i just had an engine failure . It started out with white smoke and coolant coming out of the exhaust . Checked coolant tank and it was empty. Before this i had codes p2189-p2187 which were cleared after replacing AOS. After 3 miles new code for misfire cylinder 6. I did quick search and one dealer site had replacement motor for 2008 Cayman S at $43k is this correct ? Is an engine rebuild an option with this issue of coolant in oil tank ? Anyone have any luck with LA porsche dismantled motors? Any suggestions would be greatly appreciated
Hi JFP thanks . I got the three codes mentioned above. The car has 198k . I drained the oil and there was no oil mix. Could AOS be partial problem? I’m going to check banks two cylinder 4 coil plug . Also read on some post the p0446 has something to do with bad Camshaft sensor bank 2? So if it’s emission related engine should be okay?
